Detailed implementation mode

[0022] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings.

[0023] See the attached Figures 1 to 4 Figure. The device for multi-angle and multi-size simultaneous on-line inspection shown in the present utility model has a working frame 1. Inside the working frame 1, there is a working platform 2 for adjusting the angle of the part and a visual inspection module 3 for collecting photos of the part at different angles. Among them, the working platform 2 is fixed inside the working frame 1 through a bracket 4. In the working platform 2, there is a hollow rotary platform 6 for placing the part 5. On one side of the hollow rotary platform 6, a U-groove photoelectric switch 7 is fixedly arranged, and on the other side, there is a flap 8 that rotates with the hollow rotary platform 6. At the same time, a visual inspection module 3 is arranged above the hollow rotary platform 6.

[0024] In this embodiment, an electric slide table 9 for driving the hollow rotary platform 6 to move up and down is also arranged in the working platform 2. The electric slide table 9 is installed on the bracket 4. A pallet 10 is arranged on the electric slide table 9, and the hollow rotary platform 6 is connected to the pallet 10 through a connecting piece 11. The arrangement of the electric slide table 9 facilitates lifting the part 5 to be inspected to the height of the visual inspection module 3 for inspection.

[0025] In this embodiment, on one side of the top of the connecting piece 11, there is an intermediate piece 12. A support block 13 is arranged on the intermediate piece 12, and a U-groove photoelectric switch 7 is fixedly installed on the support block 13. At the same time, the opening of the U-groove photoelectric switch 7 faces the hollow rotary platform 6.

[0026] In this embodiment, the U-groove photoelectric switch 7 is at the same height as the flap 8. When the flap 8 rotates with the hollow rotary platform 6 to the U-groove photoelectric switch 7 and extends into the slot of the U-groove photoelectric switch 7, the U-groove photoelectric switch 7 sends a switch signal to the PLC controller by sensing the flap 8 to realize the rotation control of the hollow rotary platform 6.

[0027] In this embodiment, a part placement block 14 for fixing the part 5 is arranged on the top of the hollow rotary platform 6.

[0028] In this embodiment, the vision detection module 3 includes a heightening boss 15, a shielding sheet 16, a receiver 17 and a transmitter 18. The receiver 17 and the transmitter 18 are respectively mounted on the heightening boss 15. The shielding sheet 16 is respectively arranged on both sides of the receiver 17 and the transmitter 18, and is used to isolate the influence of external light sources on internal shooting, improve the quality of the captured pictures, and the transmitter 18 faces the receiver 17 directly.

[0029] In this embodiment, both the hollow rotary table 6 and the vision detection module 3 are electrically connected to the PLC controller, and the PLC controller controls the operation. The operator only needs to complete the loading and unloading actions, and the transfer is completed by the electric slide table 9. The external feature acquisition is completed by the hollow rotary table 6 and the vision detection module 3.

[0030] When this application is in operation, the operator places the part 5 on the part placement block 14. After the placement is completed, the electric slide table 9 drives the hollow rotary table 6 to rise until the part 5 is located between the transmitter 18 and the receiver 17 of the vision detection module 3. At this time, the hollow rotary table 6 rotates, and the baffle 8 rotates with the hollow rotary table 6. When the baffle 8 first passes through the U-groove photoelectric switch 7, the vision detection module 3 starts to collect the external features of the part 5. When the baffle 8 secondarily passes through the U-groove photoelectric switch 7, the vision detection module 3 ends the collection of the external features of the part 5. At this time, the outer diameter dimension information of the part 5 is collected. The electric slide table 9 drives the hollow rotary table 6 to descend, and the operator removes the part, completing the work process of collecting the outer diameter dimension information of one part.

[0031] The above embodiments merely illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
